pub fn decode_props(raw: &str) -> Option<Map<String, Value>>Expand description
Decode the data-devup-props marker back into a props map.
Accepts both the modern base64 payload (standard alphabet) and, as
a fallback, a raw JSON object string — the TS side emits the latter
when window.btoa is unavailable (Node fallback path). Returns
None when the attribute is absent or unparseable.
